Multiple the second equation by 2 and subtract it from the first
2x + 5y = 10
2x - 6y = -12
now subtract
11y = 22
y = 2
Plug y = 2 in to either equation
x - 3(2) = -6
x - 6 = -6
x = 0
The point at where they intersect is (0, 2)
I think the parent function is
y=x
Answer:

Step-by-step explanation:
x² + 2x - 3 + y² = 5
Strategy:
Convert the equation to the centre-radius form:
(x - h)² + (y - k)² = r²
The centre of the circle is at (h, k) and the radius is r
.
Solution:
Move the number to the right-hand side.
x² + 2x + y² = 8
Complete the square for x
(Take half the coefficient of x, square it, and add to each side of the equation)
(x² + 2x + 1) + y² = 9
Complete the square for y
The coefficient of y is zero.
(x² + 2x + 1) + y² = 9
Express the result as the sum of squares
(x + 1)² + y² = 3²
h = -1; k = 0; r = 3
The centre of the circle is at 
The graph of the circle below has its centre at (-1,0) and radius 3.
Answer: O Yes; 6
Yes it is Arithmetic; the difference is 6
Step-by-step explanation:
If the numbers keep changing by the same value being added or subtracted, it is Arithmetic.
-15 - (-9) = -6 -9 - (-3) = -6 -3 - 3 = -6
"Same difference" as the saying goes!
Answer:
0.000083
Step-by-step explanation:
When you multiply by 10^-5, you're really multiplying by 0.00001. This multiplied by 8.3 is 0.000083. It also means that you just move the decimal place in 8.3 to the left five times, where you'll get the same answer.
